The correct statement established by the Northwest Ordinance is:
Only territories with the population of at least 60,000 could apply for statehood.
The Northwest Ordinance of 1787 provided a method for admitting new states to the Union and included provisions that territories needed to reach a minimum population before they could apply for statehood. It also focused on the establishment of a system of government and included principles regarding education and rights, but it did not guarantee that escaped slaves would be free.
